Embodiment
As shown in Figure 1, be the structural representation of data backup of the present invention and recovery system preferred embodiment.In the present embodiment, said data backup and recovery system 60 comprise body circuit 20, fallback circuit 22 and first memory 23.
Consult shown in Figure 2ly, said data backup and recovery system 60 are arranged in the server 2, this server 2 also comprise the Basic Input or Output System (BIOS) that links to each other through data bus (BasicInput Output System, BIOS) 21 with processor 24.In the present embodiment, said body circuit 20 is used for the main system that storage server 2 is equipped with various application programs, and said first memory 23 is used for the various data (like voice data and video data etc.) of storage server 2.In the present embodiment, said first memory 23 hard disk that can be server 2.
Consult shown in Figure 3ly, said fallback circuit 22 is a kind of slave systems of server 2 main systems, comprises second memory 25 and data backup and recovers module 26.Wherein, said second memory 25 stores the starter system 30 of the backup of server 2, the backup main system of one or more server 2 (like the first backup main system, 41, the second backup main systems, 42, the three backup main systems 43).The starter system 30 of said backup is the operating system that server 2 is pre-installed when dispatching from the factory, promptly a kind of naked system that Any Application is not installed.In the present embodiment, said second memory 25 can be a nand flash memory chip.
In the present embodiment, said data backup and recovery module 26 are used for every at a distance from a Preset Time (as 5 minutes), the main system of a server 2 of backup.If the user has the data of pair server 2 main systems to make amendment (comprise mandate with undelegated); Said data backup will be backed up data and amended data before revising with recovery module 26 simultaneously; Return to when taking place and revise preceding or amended arbitrary state, guarantee security, the integrality of system information in order to disaster.
Need to prove that in view of the consideration of second memory 25 capacity and cost, when the backup quantity of server 2 main systems reached a preset value (as 10), data backup covered the main system of backup before with the main system that recovery module 26 will be used new backup.For example; The maximal value of supposing main system backup quantity is 10, and when main system backup quantity surpassed 10, data backup replaced the first backup main system 41 with recovery module 26 with the 11 backup main system; The 12 backup main system replaced the second backup main system 42; The 13 backup main system replaced the 3rd backup main system 43 ..., and the like.
Said data backup also is used for when the main system of server 2 can't start with recovery module 26, from the second memory 25 of fallback circuit 22, recovers the main system data automatically, describes below the detailed process.
In the present embodiment; Said data backup can be divided into one or more submodules with recovery module 26; Said one or more submodule is stored in the said fallback circuit 22 and is configured to and carried out by one or more processors (present embodiment is a processor 24), to accomplish the present invention.For example, consult shown in Figure 4, said data backup with recover that module 26 is divided into data backup submodule 201, data are recovered submodule 202 and systems inspection submodule 203.The alleged module of the present invention is to accomplish the program segment of a specific function, is more suitable in describing the implementation of software in controlling computer 2 than program.
As shown in Figure 5, be the process flow diagram of the preferred embodiment of data backup of the present invention and restoration methods.
Step S1, the main system in the body circuit 20 of BIOS 21 inspection server 2 when server 2 starts checks promptly whether the main system data of server 2 is complete.In the present embodiment, if BIOS 21 can not find the boot of server 2 main systems, or this boot damages, and shows that then the main system data of this server 2 is imperfect.
Step S2, BIOS 21 judge whether the main system of server 2 can start.In the present embodiment, if the main system data of this server 2 is imperfect, show that then the main system of this server 2 cannot start, BIOS 21 sends data restore instruction, execution in step S3 then to fallback circuit 22.If the main system complete data of this server 2 shows that then the main system of this server 2 can start, direct execution in step S4-S7.
Step S3 after data recovery submodule 202 receives above-mentioned data restore instruction, obtains the starter system 30 of server 2 backups, then execution in step S4 from the second memory 25 of fallback circuit 22.
Step S4, BIOS 21 maybe is somebody's turn to do collection system guidance information the starter system 30 that backs up from the main system of this server 2.In the present embodiment, said system bootstrap information is meant the system bootstrap routine of this server 2.Particularly, if the main system of server 2 can start, BIOS 21 collection system guidance information from the main system of this server 2 then; If the main system of server 2 cannot start, BIOS 21 collection system guidance information from the starter system 30 of the backup of this server 2 then.
Step S5, BIOS 21 be according to the system bootstrap information of collecting, and the main system that starts to server 2 is the starter system of this backup maybe.Particularly, if the main system of server 2 can start, then BIOS 21 directly starts this main system; If the main system of server 2 cannot start, then BIOS 21 starts the starter system 30 of the backup of this server 2.
Whether the main system that step S6, systems inspection submodule 203 judge this server 2 maybe starter system of this backup is naked system.If the main system of this server 2 maybe starter system of this backup is not naked system, then execution in step S7; If the main system of this server 2 maybe starter system of this backup is naked system, then execution in step S8.The main system that is appreciated that this server 2 is not naked system, and the starter system of these server 2 backups is a kind of naked systems.
Step S7, server 2 executive system tasks are controlled the execution of various application programs, and flow process finishes.
Step S8, data are recovered submodule 202 obtains server 2 backups from the second memory 25 of fallback circuit 22 main system, and the main system that will back up sends the body circuit 20 of this server 2 to, restart server 2 then, and return step S1.In the present embodiment, said data backup submodule 201 is every at a distance from a Preset Time (as 5 minutes), and the main system of a server 2 of backup backs up main system 43 or the like like the first backup main system 41, the second backup main system 42 and the 3rd.
In the present embodiment, data are recovered submodule 202 obtains server 2 the last backups from the second memory 25 of fallback circuit 22 main system.For example; Consult shown in Figure 3; The BACKUP TIME of supposing the first backup main system 41 is 10:20, and the BACKUP TIME of the second backup main system 42 is 10:25, and the BACKUP TIME of the 3rd backup main system 43 is 10:30; Then data are recovered submodule 202 selections the 3rd backup main system 43, and send the 3rd backup main system 43 the body circuit 20 of this server 2 to.
In other embodiments, if the 3rd backup main system 43 still can not start, then continue to start the second backup main system 42.If this second backup main system 42 still can not start, then continue to start the first backup main system 41 ..., and the like, all the backup main system circulations in the second memory 25 of fallback circuit 22 finish.
What should explain at last is; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spirit and the scope of technical scheme of the present invention.
